What is question number game?

As an AI language model, I am not aware of any specific "question number game". However, if you are referring to number games that involve asking and answering questions, then there are many different types of these games.

One popular number game that involves questions is called "20 Questions". In this game, one person thinks of a person, place, or thing, and the other players take turns asking yes-or-no questions in an attempt to guess what the answer is within 20 questions or less.

Another number game that involves questions is "Number Puzzle". In this game, a player thinks of a number between 1 and 100, and the other players take turns guessing what the number is. After each guess, the player who thought of the number responds with "higher" or "lower" until the correct number is guessed.

Other number games that involve questions include "Guess the Number", "Who Am I?", "Math Quiz", and "Trivia Challenge". These games can be played alone or with a group of people, and they can be customized to fit different skill levels and interests.
